Method Details

execute

public final TruffleString execute(String value,
 TruffleString.Encoding encoding)

Creates a TruffleString from a Java string, re-using its internal byte array if possible.

Since:

22.1

execute

public abstract TruffleString execute(String value,
 int charOffset,
 int length,
 TruffleString.Encoding encoding,
 boolean copy)

Creates a TruffleString from a given region in a Java string, re-using its internal byte array if possible and the region covers the entire string. If copy is false, the Java string's internal byte array will be re-used even if the region does not cover the entire string. Note that this will keep the Java string's byte array alive as long as the resulting TruffleString is alive.

Since:

22.1

create

public static TruffleString.FromJavaStringNode create()

Create a new TruffleString.FromJavaStringNode.

Since:

22.1

getUncached

public static TruffleString.FromJavaStringNode getUncached()

Get the uncached version of TruffleString.FromJavaStringNode.

Since:
